In fact, kvm doesn't seem to make any progress at all :(. I'm
currently going through the "microsoft update" dance on a VM there,
and I literally left for an hour during which there was no progress
because the QEMU window wasn't visible.
Even stranger, if I minimize the QEMU window and then switch
workspaces, it gets plenty of cycles.
